I just realized that you hadn't said who are you sourcing the
drivers from ? It appears that your only concern is the cabinet. Yes that is what makes them special from the visual perspective and possibly important resonance control, but the drivers and your crossovers not tp mention the other electronics should be considered with equal deep concern. If they look great but sound like crap I think you'll sell a few pairs to interior designers perhaps but no uudio lovers will bother with them. So what drivers are you using? (not just sizes etc, )
